European Strategic Noise Maps for Large Departmental Roads Aggregated from Type A Data

Aggregated geospatial data representing noise exposure from major road infrastructure, created under the European Directive 2002/49/EC. The dataset, aggregated by CEREMA using the QGIS MIZOGEO plugin, identifies areas exceeding specific noise indicators for day-evening-night and night periods. It was last updated by the Bureau de Recherches Géologiques et Minières in May 2021.

Use Cases

• Assess population exposure to road traffic noise based on Lden and Ln indicators.
• Establish baseline noise levels for Urban Travel Plans (UDPs) to identify areas needing traffic management.
• Supplement Local Planning Plans (LDPs) with graphic noise exposure information.
• Identify areas exceeding 55 dB(A) Lden and 50 dB(A) Ln thresholds for strategic noise management.

Strengths

• Data is structured according to the harmonized assessment framework of EU Directive 2002/49/EC.
• Aggregation was performed using a specific, documented tool (QGIS MIZOGEO plugin by CEREMA).
• Source organization (CEREMA) is a recognized public institution for environmental expertise.

Limitations

• Description metadata is limited; actual data quality, column definitions, and file formats require manual inspection after download.
• Last updated 2021-05-03 00:00:00; freshness should be verified for current applications.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
